Germination and Seedling Growth of Hybrid and Madura Local Corn on Salt Stress

Abstract

Madura Salt Tolerance Corn (var. Duko and var. Elos) and Hybrid Corn (Sukmaraga and Anoman-1) were germinated on 0, 100, 200, 300 and 400 mM NaCl for 7 days. Then its planted by wick system hydroponic also on the same NaCl concentration for 14 days, conducted by using randomized block design with 4 replications. The results were all varieties couldn't germinated on 300 and 400 mM NaCl and Anoman-1 couldn't be germinated from 200mM NaCl. Duko had the highest value of Full Germination Percent (FGP), Mean Germination Time (MGT), Germination Index (GI), and Salt Tolerance Index (STI) at 200 mM NaCl. Sukmaraga had the highest value of height and shoot growth ratio of the seedling.
